[0010]According to the embodiment, the magnetic substrate is spaced apart from the coil part by the bonding layer, so that the antenna performance can be improved.
[0011]According to the embodiment, the coil part is directly provided on the top surface of the non-magnetic insulating substrate through the laminating and etching processes, so that the fabrication process of the antenna assembly can be simplified.
[0012]According to the embodiment, the inner terminal of the spiral antenna pattern is connected to the connector provided at the outside of the spiral antenna pattern through the conductive bridge, so that the fabrication process of the antenna assembly can be simplified.
[0013]According to the embodiment, the extension pattern of the antenna pattern is cut out together

Abstract
Disclosed is an antenna assembly including a substrate, and a wireless charge antenna pattern on the substrate. The wireless charge antenna pattern has a sectional surface including a plurality of inner angles in which two inner angles are different from each other. The antenna assembly includes a wireless communication antenna pattern formed on the substrate and provided at an outside of the wireless charge antenna pattern. The wireless communication antenna pattern has a plurality of inner angles at a sectional surface thereof, and a plurality of angle values of the inner angles provided at the sectional surface of the wireless communication antenna pattern correspond to a plurality of angle values of the inner angles provided at the sectional surface of the wireless charge antenna pattern, respectively.
Description
TECHNICAL FIELD[0001]The disclosure relates to an antenna assembly and a method of manufacturing the same. More particularly, the disclosure relates to an antenna assembly including an antenna, which is wirelessly rechargeable, and a method of manufacturing the same.BACKGROUND ART[0002]A wireless power transmission or a wireless energy transfer refers to a technology of wirelessly transferring electric energy to desired devices. In the 1800's, an electric motor or a transformer employing the principle of electromagnetic induction has been used and thereafter attempts have been performed to transmit electrical energy by irradiating electromagnetic waves, such as radio waves or lasers. Actually, electrical toothbrushes or electrical razors, which are frequently used in daily life, are charged based on the principle of electromagnetic induction. The electromagnetic induction refers to a phenomenon in which a voltage is induced so that a current flows when a magnetic field is varied aro...
